rl his invention relates to harness cords for looms and itis the generalobject of the invention to provide a. durable form of attachment etweena harness frame and a harness cord formed of tiller cord.

Triarness frames of looms are raised and lowered by means of one form oranother of mechanism, such as heads, -dobbies or cams, the lifting forcebeing transmitted through flexible connections which pass over pulleysor sheaves carried in the arches of the loom. It is an important objectof my present invention to provide means including a head which is soclamped to the steel cable core of the tiller cord as to be forced intothe outer fibrous covering of the cord.

It is a further object of my present invention to remove a portion ofthe fibrous covering for the steel cable core and pass the same throughthe head, wrapping the cable upon itself and then binding it tightlybetween the head and a portion of the tiller rod.

A still further obj ect of my present invention is to provide improvedconnections between the cable and the head wherein the cable is heldwithin the periphery of the head so as not to project where it may havecontact with adjacent cords or other moving parts of the loom.

l/ilith these and other objects in view which will appear as thedescription proceeds, my invention resides in the combination of partshereinafter described and set forth in the claims.

lllhe loom frame or arch 10 has a pin 11 on i which is mounted aplurality of harness sheaves, one being designated herein at l2. Harnessframes 13, one of which is shown in Fig. l, are raised and lowered bymeans of mechanism not shown to form the sheds between the warp threads.Heretofore, it has been customary to effect raising and lowering of theharness frames through flexible connections such as small rope orleather straps. Each harness frame is provided with a hoolr 14 which hasconnection with the flexible lifter.

ln carrying my invention into eect I provide each harness frame with astrap or connector 20 formed of tiller cord, the same having a core 2lwhich is made up of several strands of iieirible relatively fine steelwire. Surrounding this cable is a sheath of iibrous material 22 whichresembles the ordinary cord used in certain classes of looms.

l remove a portion of the sheath 22 and extend the core or cable throughholes 23 and 24- formed in a head or connector 25 which is preferablysheet steel. The portion of the connector' between the holes isydepressed as at 26 in Fig. 2. The end of the cable is passed firstthrough hole 23, then over the depressed portion 26, and then throughthe other hole 23, being bent back under the depressed part 26 andwrapped around a portion of itself between the depressed part and thesheath 22, as designated at 27.

In F ig. l I have set forth one of the steps in the manufacture of mycord and connector, the edges 28 and 29 being separated to define asubstantially U-shaped cavity into which the fibrous covered end of thecable may extend, as in 6. After the steel core has been manipulated asdescribed the straight end 30 will. be extended along that part of thesheath 22 which lies in the cavity defined between the edges 28 and 29.By means of appro priate tools these edges are then closed so that thehead assumes the cylindrical form shown in cross section in Fig. 5.

The head is so proportioned that the edges 28 and 29 will force the end30 into the fibrous sheath 22, as clearly shown on enlarged scale inFig. 5. It is by the construction set forth in this latter figure that Iam enabled to anchor the end of the steel core securely and at the sametime prevent the fibrous sheath from working loose and drawing out ofthe head. The head ma)- have an extension with la perforation all toreceive the hook 14.

From the foregoing it will be Seen that I have provided a very simpleconnection between a harness frame and tiller cord which includes a headhavingi two holes through which the cord of the tiller top extends. Thehead has a depressed part between the holes over which the core extends,so that the latter will not project substantially beyond the peripheryof the head. It will also be seen that by wrappingr the cord arounditself as at 27 I provide additional friction the effect of which is toprovide a tight bind tending to prevent the core from workingr loose.Furthermore, the end 30 of the cable is so placed as to retain thesheath of fibrous coveringlr 22.

Having thus described in v invention it will be seen that changes andmodi tications mayY be made therein by those skilled in the art withoutdepartingr from the spirit and scope of the invention and I do not wishto be limited to the details herein disclosed, but what I claim is:

1. In a connector for loom harnesses, a flexible cord havin;r al fibroussheath and a wire core, a head havingy holes through which the coreextends, the core being wrapped on itseltl and beiner held embedded inthe sheath by a portion of the head.

2. In a connector for loom harnesses, a flexible cord having: a fibroussheath and a wire core. the sheath beiner removed near the. end of thecord and the core extendingr uncovered. a head through which the coreextends, the end of the core lyingT between the head and sheath andbeing held embedded in the latter by the head.

3. In a connector for loom harnesses, a fiexible cord having a fibroussheath and a wire core, a sheet metal head havingr a cylindrical portioninto which both the sheath and the core extend. said head havingholding: engagement with the core, the core beingY wrapped around itselfand then extending between the sheath and the cylindrical portion of thehead and beingY held embedded in the sheath b v the head, wherebvv thesheath and end of the cable are held against relative movement withrespect to each other.

4. In a connector for loom harnesses, a flexible cord havingir a fibroussheath and a wire core, a head having a hollow cylindrical body providedwith a pair of spaced openings, the part of the head between theopenings being depressed` the wire core extending through the openingsand alonei4 the depressed part of the head, so that said core liessubstantially within the periphery ot' the head, the core being: wrappedon itself and terminating within the head.

5. In a connector for loom harnesses, a flexible cord having a fibroussheath and a wire core, a head having a hollow cylindrical body providedwith a pair of spaced openings, the part of the head between theopenings being depressed, the wire core extendinpr through the openingsand. along the depressed part of the head, so that said core liessubstantially within the peripheryv of the head, the core being wrappedon itself and terminating within the head, heilig held between theinterior of the head and the sheath.

In testimony whereof I have hereunto affixed my signature.
